Description of intervention(s) / exposure
This study will observe people who have had a concussion presenting to a concussion provider through the New Zealand Accident Compensation Corporation (ACC) Concussion Service, when it is suspected the neck is contributing to their symptoms, at the time they present to a Physiotherapist for neck assessment and treatment.
Participants will complete neck Physiotherapy as normal. This will involve a detailed assessment of the neck including movements, palpation and tests. Treatment will be decided by the participant in collaboration with the Physiotherapist and may include hands-on therapy, exercise, education, advice etc. Treatment will typically span several sessions (e.g. 6 sessions), and is expected to be completed within 2 months of their first appointment. Again, this will be decided by the participant along with the Physiotherapist and healthcare team.
Standardised outcomes will be measured at the initial Physiotherapy visit, and again at the final Physiotherapy visit. This will involve questionnaires, clinical measures of symptoms and function, clinical findings in the neck, and saliva samples. Descriptive findings, treatment and outcomes will be retrieved from the clinical notes at the end of their neck Physiotherapy treatment.

Eligibility
Key inclusion criteria
These are: Patients presenting through the ACC Concussion service to APM Limited OR Advantage South concussion assessors with persistent (> 10 days) headaches, dizziness and/or neck pain; subjective history suggesting the neck may contribute to their symptoms*; who accept and follow through with a referral for neck assessment and treatment by a Physiotherapist with postgraduate manual therapy training.
*Potential for the neck to contribute to patient’s symptoms will be informed by:
1. Increased neck pain or stiffness since their concussion injury OR
2. Headache consistent with symptoms arising from the neck: headache triggered by neck movement/positioning, or external pressure to the neck/head; restricted neck range of movement; neck, shoulder or arm pain on the same side (Sjaastad, Fredriksen, and Pfaffenrath 1998) OR
3. Dizziness consistent with symptoms arising from the neck: non-rotatory dizziness described as imbalance or unsteadiness; and triggered by neck movements or positions (Reid et al. 2014).

Statistical methods / analysis
In line with recommendations for a prospective case series the main analysis will be descriptive rather than statistical (Carey and Boden 2003; Kooistra et al. 2009). Patient characteristics and flow through the study will be reported, including loss to follow-up and other potential areas of bias.
Outcome measures will be tabulated for easy comparison of cases, and common clinical features of the neck contributing to people’s symptoms will be discussed. Changes in outcomes pre and post manual therapy will be reported, identifying and discussing common themes. Where appropriate, basic statistical analysis comparing pre and post manual therapy outcomes may be performed (e.g. paired t-test). Note that statistical analysis is not designed to establish causal effects or treatment efficacy, but to identify areas where manual therapy has an impact on participant’s symptoms.
For these purposes a target study sample of 30 participants was discussed and agreed upon by the research team. Note that as this is a descriptive case series this number is not based on power calculations for statistical analysis, but numbers considered achievable and appropriate for descriptive purposes.
The levels of cortisol and testosterone in all the salivary samples will be measured using commercially available ELISA kit (Salimetrics, USA) according to the manufacturer’s instruction. This will be performed at the Department of Physiology, University of Otago.
The feasibility aspects of the research will be reported and discussed based on the quality and quantity of data collected over the study period. This will also inform service delivery.
